SURFACE CONDENSER.

Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed June 21, 1904.. Serial No. 213,570.

To aZZ whom it may concern.-

Be it known that I, FRANK SMEDLEY FARNS- WORTH, a subject of the King ofGreat Britain and Ireland, and aresident of The Oaklands, Mickleover, inthe county of Derby, England, have invented a certain new and usefulImproved Surface Condenser for Steam- Engines. (for which Letters Patenthave been applied for in Great Britain in the name of Alfred WilliamFarnsworth as a communication from me when abroad, said applicationbeing numbered 23,789 and dated November 3, 1903,) of which thefollowing is a specification.

The object of my invention is to provide a device or means of obviatingthe defects of p the ordinary types of marine or land surfacecondensers.

Referring to the drawings, which form a part of this specification,Figure 1 is a part: sectional elevation of two sections of one type ofmy invention, as will be hereinafter explained. Fig. 2 is a diagrammaticplan drawn to a smaller scale, showing one application of a number ofsections of my improved condenser of the type shown on Fig. 3. Fig. 3 isa part-sectional elevation of two sections of another type of myinvention, as will also be hereinafter explained.

In carrying out my invention 1 construct my improved condenser insections a. Each section is separate and distinct, but of the samepattern, and can be readily cut off and isolated from any or all of theother sections, as described hereunder. Thus when cleaning, testing,repairing, or other operations have to be performed each or any of thesections may be isolated from the other sections of the condenser andthe operation carried out without interfering in any way with the properand effective working of the other portions or sections. These sectionsa may be of any size, shape, or number, but are preferably all of onepattern in the same condenser. They may be either vertical or horizontalor inclined to any angle and assume any position or grouping that may bedesirable to suit the proposed position of the condenser, an example ofone form of grouping that may be arranged being illustrated by thediagrammatic plan of Fig. 2. They may be made of cast-iron,wrought-iron, steel, brass, or any other suitable metal or mixtures ofmetals or metals and other materials, as may be found most desirable.They will be filled with tubes Z), as is customary in surfacecondensers, which may be of brass, copper, or any other suitable metaland may be of round, square, or other desired section, arranged in anyconvenient position according to the shape of the sections. The steamwhich is to be condensed may be allowed to pass either through oroutside of the tubes 6, as may be desired, the connections from theexhaustpipe 0, circulating-water inlets (Z, circulatingwater outlets c,and air-pump suction f being varied to suit.

Each section a is isolated from any or all of the other sections,circulating-water inlets (Z, outlets c, exhaust-pipes c, and air-pumpsuction f by means of gate or other approved valves 9. Suitable pet orother cocks h are provided for each section a.

By closing the gate or other valves g in the pipes connecting anysection or set of sections a to the remaining section or sections of thecondenser steam and the circulating water may be prevented fromcirculating through the first-named section or sections, and anyoperation of cleaning, testing, repairing, or the like may be readilyand easily conducted by taking out the section or sections thus isolatedwithout interfering with the proper and efficient working of that partof the condenser not cut off from the steam and water supply, and,further, by making all the sections of one condenser of the same patternonly that particular form of section need be stored for repairs.

Auxiliary condensers may be dispensed with where my invention is used,since one or more sections only may be used when otherwise an auxiliarycondenser would be employed, a suitable arrangement of the pipes andvalves being made to allow of this.

As all cooling-surfaces will have an even distribution of steam, eachsection receiving its due share, less circulating water will be requiredthan in the case of the condensers commonly used to maintain the samevacuum.

By the use of sheet metal in building the sections of my condenser theymay be made lighter per square foot of cooling surface than any otherform of condenser.

It will be noticed that in arranging the sections of my improved surfacecondenser in the manner illustrated no long connectingpipes are usedbetween the main exhaust-pipe and sections, so that the steam isdistributed over the sections in the most efiicient manner to produce ahigh vacuum and keep the condensed water at a high temperature.
